Title: Shields for anodes
Inventor: TROMANS BENJAMIN
IPC: C25D17/10
Filed: 1960-09-06
Abstract: 911,684. Anode shields. CANNING & CO. Ltd., W. Aug. 29, 1961 [Sept. 6, 1960], No. 30667/60. Class 41. A shield for an electro-plating anode formed from titanium, with or without a coating of platinum, shaped as a cap or part-cap fitted over the top of the anode and descending to cover, at least, opposite sides of the anode in the region containing the screw-threaded part of the suspension member. For example, Figs. 1 and 2, are side elevations of two anodes 6 of elliptical cross-section showing the shields 8 and 10, conducting suspension rods 7 screwed into the anodes 6, and rubber or plastic sleeves 9 which hold the shields in position. The clearance between the skirt or flanges and the anode is not more than “ inch and the area covered extends downwardly to at least half of the depth of the screw-threaded hole in the anode. The titanium shield, combined with an electrically conductive suspension member screwed into the anode, is for use with plating solutions other than those based on fluoborate, fluoride or sulphamate salts and its application to nickel or copper anodes in nickel or copper plating solutions is cited.

Title: Improved circuit arrangement employing cathode ray tubes
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H01J29/02
Filed: 1950-12-16
Abstract: 711,275. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 6, 1951 [Dec. 16, 1950], No. 30712/50. Class 39(1) An electric circuit arrangement employs a cathode-ray tube comprising an electron gun, a target having a signal electrode, and between the gun and the target an anode electrode and electromagnetic deflecting means surrounding the anode, wherein the anode is formed in two spaced annular parts and the deflecting means surrounds the anode part remote from the signal electrode, the circuit including means for maintaining each of the anode parts at substantially the same high direct potential, and means for effectively connecting the anode part nearer the signal electrode to earth for high frequencies whereby the pick-up of spurious signals by the signal electrode due to voltage fluctuations induced in the anode by the deflecting means is substantially reduced. As shown in Fig. 2 the anode may comprise two coatings 10 and 13 connected by a resistance 20 which may be a sensitive coating on the shoulder of the envelope. The coatings are thus at the same direct potential but high frequency currents induced in the coating 10 by the deflecting coils 17 are prevented from reaching the coating 13 and influencing the target 9. An exterior coating 21 connected to an earthed shield 19 may be provided to give a capacitive earth connection for the coating 13. In a modification, Fig. 3 (not shown), the resistance 20 is omitted and the coating 13 is connected through the envelope to an exterior strip conductor which extends along the envelope as far as the target electrode and is connected to an H.T. supply; a shield connected to the shield 19 surrounds the coating 13, the shoulder of the tube, and part of the coating 10. In a further modification, Fig. 4 (not shown), the coating 13 is provided with a lead extending through the envelope and connected by a wire extending along the outside of the envelope to the lead-in conductor 12 which is connected to the coating 10; the wire may be enclosed in an earthed electrostatic screen. An ion trap grid may be connected to the coating 13.

Patent GB-309033-A (GB)
Abstract: 309,033. I. G. Farbenindustrie Akt.- Ges. April 3, 1928, [Convention date]. 2-Aryl.4- : 6-dihydroxypyrimidines or their homologues or substitution products are prepared by heating a free aryl carboxylic amidine base with an ester of malonic. acid. Thus 4- or 3-nitrobenzamidine is converted to an aryl dibydroxypyrimidine by heating with the diethyl ester of malonic acid. The hydroxy groups are replaced by chlorine by the action of phosphorus oxychloride. The amidines from m- and p-tolu Iic acids, halogen benzoic acids and naphthoic acid are mentioned as starting materials. Aromatic amidine bases in the free state are obtained by dissolving the corresponding aryl nitrile in an equivalent amount of ethyl alcohol and adding an equivalent proportion of free hydrochloric acid to obtain the imino-ether of the formula- This is treated with ammoniacal methyl alcohol and the alcohol distilled off to leave the free base as residue.

Abstract: 1362022 Mineral-mining installations GEWERKSCHAFT EISENHUTTE WESTFALIA 5 July 1971 [8 July 1970] 31308/71 Heading E1F A method of mining minerals comprises heating a mineral face by heaters that are then moved away from the face in a predetermined sequence so that the removal of at least one of the heaters allows of operation of cutting means on the heated mineral. The apparatus for carrying out the method involves combining with a longwall mining installation in which cutting means, e.g. a plough 30, is moved along a face conveyer 1 advanceable by an associated ram and roof-propping system 57, 2 heaters 5 of which one or more can be displaced transversely of the conveyer. Preferably one or more heaters are reciprocable by a jack 7, 8 in a frame 6 pivotally carried by legs 11, 12 pivoted to the roof-propping system 57. The height of the frame can be varied by actuation of a jack 19 acting between the leg 12 and the roof-propping system 57. Control means are provided for limiting advance of the heaters towards a face, for causing appropriate withdrawal of the heaters to allow of passage of the cutting means past the heaters, and advance of the installation as mineral is mined from the face.

Abstract: 856,638. Fluid-pressure brakes. HAMPEJS; K. Oct. 9, 1957, No. 31565/57. Class 103 (1). A driver's brake valve for a two-circuit compressed-air braking system comprises a body formed of three parts 1, 2, 3 which, when clamped together form a mounting for diaphragms 4, 5, the first diaphragm 4 being connected to a first piston 6 and the second diaphragm being connected to a second piston 18, the first piston being adapted to move downwardly when the piston 11 is displaced by means of an actuating force in the direction of the arrow shown to lift valve member 16 away from seat 17 and permit compressed-air to flow between a first air reservoir connection 14 and a connection 39 to the brake cylinders of the first circuit. The increase in pressure in the second cylindrical chamber 12 causes the second piston 18 to move downwardly against the action of an adjustable spring 23 to open a second valve member 26 and permit flow of compressed-air from compressed-air reservoir connection 22 to the connection 40 to the brakes of the brake cylinders of the second circuit. Should pressure fail in the first circuit movement of the first piston 6 will cause thrust rods 29, which rest on the top surface of the piston 18, to be engaged by the underside of piston 6 to thereby depress the second piston 18 and open valve member 26. Adjustment of the spring 23 by means of a regulating screw 24 ensures a time lag or pressure lead of the first circuit.

The tuning pointer comprises a rod 26 of glass, quartz or other lightconducting material carried by a hood 28, a lamp 30 within the hood illuminating the pointer by internal reflection. The pointer is etched or otherwise made light diffusive as above described along a preferably coloured line 26a adjacent the translucent dial 16 which is formed of translucent slats 18, 20, 22 joined edge to edge by opaque layers 19, 21. Each slat 18, 20, 22 bears a wave range scale S and is distinctively coloured. A knob 74 operating the wave-range switch 76 also rocks a shutter 50 through gearing 70, 68 and shaft 58 whereby only the appropriate wave range scale is illuminated through the shutter aperture 52 by lamps 64 carried by the shutter frame. The dial may be plane or arcuate as shown, and' the pointer which is shaped to correspond is driven along a guide 34 through an endless cord 40 from the tuning shaft 48. In alternative constructions, the pointer may illuminate the dial by light emerging at one end thereof, or it may be bent at the remote end into a circle and made light diffusive around the inner periphery of the circle to produce a circular light spot adapted to register with similarly shaped scale markings on the dial. Parts of the pointer may be masked. Specifications 202,707, [Class 106 (iv)], and 475,379 are referred to.
